Question

If the mass m(x) (in kilograms) of a thin rod of length x (in metres) is given by, m(x) = 3x
then what is the rate of change of mass with respect to the length when it is x=3 and x = 27
metres​

Answer 1

See the attachment

The change of mass is defined by delta m that is. m2 - m1

By taking values of x we can find it.

.Two values are coming u can take one
